Question

Сколько значений переменной x может быть для каждой переменной y?

Answer 1

Если не ошибаюсь, то одно- два или вообще не иметь

Answer 2

The question is a bit ambiguous, but I'll try to clarify and provide an answer.

If we have a single variable "y" and its value can be any real number, then the variable "x" can also take on any real number for each value of "y." In this case, there are infinitely many values for both "x" and "y."

If you meant something else or have a more specific context in mind, please provide additional information, and I'll be happy to help further.
